Manufacturing is one of the largest industries in the United States, accounting for approximately 11% of GDP. Almost everything we enjoy on a daily basis – whether it’s the car we drive or the television we play video games on, is made possible because of manufacturing companies.

Due to global competition to produce the highest quality goods, cheaper and faster, manufacturing also tends to be a breeding ground for innovation. This innovation can take many different forms, including cutting-edge robotics, artificial intelligence, and methods for precise machining. As an industry that’s heavily involved in research and development, manufacturing companies are uniquely positioned to take full advantage of R&D tax credits to help offset some of their research costs.

How does a manufacturing company qualify for the credit?

There is a four-part test used to determine whether a company has a project that qualifies for the R&D Tax Credit. If you have a project that meets each of the four quadrants below, your project most likely qualifies.

Technological in nature

  • Discover information that fundamentally relies upon principles of Hard Sciences (i.e. Physical Sciences, Biological Sciences, Engineering, Computer Science, etc.)
  • Not social, economic, or psychological Permitted Purpose

Permitted Purpose

  • Develop a new, or improve an existing, product or process
  • Related to Functionality, Performance, Reliability, Quality, Significant cost, Savings, etc.
  • Not Aesthetics 
Four Part Test

Eliminate Uncertainty

  • Capability
    • Uncertain if able to achieve desired result
  • Methodology
    • Uncertain of optimal design or process to achieve project goals
  • Goals to show there were issues and potential alternate solutions

Process of Experimentation

  • Evaluate and test alternative design or process to identify optimal solutions
  • Methods to use
    • Prototyping
    • Modeling
    • Systematic Process of Trial and Error Simulation
    • Computer Science Testing (Validation, Beta, etc.)

Once a company determines that their project meets these criteria, three expense categories factor into the tax credit calculation:



Contract Research

Manufacturing companies can qualify for the R&D tax credit regardless of the type of production they specialize in. While not all-inclusive, a few examples of manufacturing companies that could claim the tax credit include:


With the rise of big tech and the massive fortunes generated by software companies each year, computer engineering is perhaps the most fast-paced, dynamic industry in the United States. Startups and large software corporations, alike, are in a constant R&D battle to innovate the next big thing or be rendered obsolete. Qualifying R&D activities that a computer engineering company might partake in include:

As aircraft designs are constantly evolving to meet the demands of a society who wants to travel cheaper, faster, and with less of an environmental impact, R&D will always be a key aspect of the aerospace industry.

The chemical industry is responsible for taking raw materials that can be found in nature, such as metals, minerals, and oil, and converting them into a form that can be utilized in some way by society. Without the chemical industry, most manufacturing processes in other industries would be impossible. Chemical manufacturers spend large amounts of money on R&D in order to improve the production process for the chemicals that they produce, as well as working to develop new chemicals and chemical applications. A few examples of qualifying R&D activities include:

The opportunities are endless – whether your company designs space shuttles or sewer pipelines, you are likely eligible to take advantage of the R&D Tax Credit.

Medical Equipment

Never has the need for a steady supply of medical equipment been so apparent than with the Covid-19 pandemic. Seemingly overnight, companies who manufacture necessary medical supplies like ventilators, examination gloves, and masks were forced to kick production into overdrive. Many manufacturers in non-medical industries have recently pivoted their production to help meet the high demand for certain medical products such as PPE decontamination units. Before the pandemic, R&D within the medical manufacturing industry was still very important – as health issues are constantly evolving, companies must also quickly evolve to stay ahead of the curve. A few examples of qualifying R&D activities within the medical equipment manufacturing industry include:

As structural engineering is largely trial and error during the design process, almost every structural engineering project has a strong case for claiming the R&D Tax Credit.

Job Shops

Job shops conduct specialized manufacturing, where instead of churning out identical products 24/7 on an assembly line, they receive drawings, specifications, or other instructions for a given system or product and work to provide a final manufactured product that meets these requirements. Sometimes this may involve a single component while in other situations a customer may require a batch of a given component. There are many tasks regularly performed by job shops which qualify as R&D. Some of these qualifying activities include:

Job shops can increase the quality of their products, cut production costs, and increase throughput by developing new, innovative ways to conduct business. Many of these activities qualify for R&D Tax Credits, which provide an additional incentive to conducting the research.

Plastic Injection Molding

Plastic injection molding is a manufacturing process that involves injecting molten materials, most often a thermosetting polymer, into a mold. Once the melted polymer cools, it hardens to form the shape of the mold and is subsequently removed. Due to the widespread application of plastics, this technology is used in many different industries. With the rise of 3D printing technologies, the plastics industry in general has become a very hot industry for R&D. 3D printing makes it possible to create plastic forms without the need to create a metallic mold, which provides flexibility and reduced cost for specialized plastic forms. Many activities in the plastics industry qualify as R&D. Some of these activities include:

  • Designing and fabricating molds to be used to create a given plastic product.
  • Modeling plastic molds in autoCAD or SolidWorks software.
  • Experimenting with new polymers to inject into the molds.
  • Integrating 3D printing technologies into the production facility for specialized forms.
  • Automating certain manufacturing processes with robotics.
  • Optimizing the production process by testing different temperatures, pressures, or other conditions that factor into the final product.
  • Using structural modeling programs to test the integrity of injection molded products.

Whether your company is working to optimize your existing injection molding process or integrating new technologies like 3D printing into your operation for specialized tasks, many of the costs incurred to perform this R&D qualify for tax credits.
